That's not really true; in 3.7, PNG is written with gamma encoding by
default, too (depending on an ini file setting)- but you won't see any
difference in brightness compared to linear encoding in most image
viewers, because indeed gamma information is written to the file header.
BTW it's not even a good idea to use linear encoding for PNG, as it is
more prone to banding artifacts (unless you use an unconventionally high
bit depth), and may also look different than intended with a few image
viewers that ignore the gamma information in the PNG header.
