The “0.88 QuickTime gamma bug” is a long-known issue where video encoded or tagged through certain QuickTime-based workflows can display too bright, washed out, and lower-contrast outside the environment it was intended for. In practice, blacks look lifted and the whole image loses density. Applying a gamma correction around 0.88 is often used as a rough fix.
