It does show Torpedo 8 getting wasted but it is a pretty abbreviated (like most of the movie). It does not make it clear though that the zero where at altitude and got drawn down by them. There is a comment (as noted, how the movie explains some things) from a Japanese commander on how the fighters need to "stop glory hunting" and get back to covering the fleet.
I am not sure where they got "glory hunting" as it doesn't really fit into the importance of what was going on (they dove down to protect the ship and where caught at low altitude when the Dauntless squadrons arrived). I suspect this may be the result of the Chinese financing (which is most assuredly at the will of the central government) though and making the Japanese looks as bad as possible (they were low because they so much valued "glory" over the protection of the fleet).
There is not to much for the Japanese, in real life, to be proud of in anything depicted in this movie. There is little need to make anything up. Probably why it was easy to get the Chinese to finance it.
There is also a scene of the Japanese (at very low altitude of course) bombing civilians as retaliation for protecting the Doolittle raiders (all very rushed). This may be inspired by the financing, but is also VERY much inline with what the Japanese did (maybe not specifically) and in reality and also VERY much underplays their revenge (you may have heard of the Rape of Nancheng):

...“They shot any man, woman, child, cow, hog, or just about anything that moved, They raped any woman from the ages of 10 – 65, and before burning the town they thoroughly looted it.”
He continued, writing in his unpublished memoir, “None of the humans shot were buried either, but were left to lay on the ground to rot, along with the hogs and cows.”
The Japanese marched into the walled city of Nancheng at dawn on the morning of June 11, beginning a reign of terror so horrendous that missionaries would later dub it “the Rape of Nancheng.” Soldiers rounded up 800 women and herded them into a storehouse outside the east gate. “For one month the Japanese remained in Nancheng, roaming the rubble-filled streets in loin clothes much of the time, drunk a good part of the time and always on the lookout for women,” wrote the Reverend Frederick McGuire. “The women and children who did not escape from Nancheng will long remember the Japanese—the women and girls because they were raped time after time by Japan’s imperial troops and are now ravaged by venereal disease, the children because they mourn their fathers who were slain in cold blood for the sake of the ‘new order’ in East Asia.”...
...Those discovered to have helped the Doolittle raiders were tortured. In Nancheng, soldiers forced a group of men who had fed the airmen to eat feces before lining up ten of them for a “bullet contest” to see how many people a single bullet would pass through before it stopped. In Ihwang, Ma Eng-lin, who had welcomed injured pilot Harold Watson into his home, was wrapped in a blanket, tied to a chair and soaked in kerosene. Then soldiers forced his wife to torch him...
So.... you can kind of understand the attitude the Chinese have for the Japanese (although none of those people are alive now).
There is a lot more in that article, including some info on Unit 731, which was really inline with some of the worst of what the Nazi's did.
