Yes, you can. "Perceptually lossless" compression is a type of lossy
compression.
> But you don't know if something is lossless or perceptual lossless.
Sure you do, if you run a diff on the data in numerical form. The only thing
"perceptual lossless" means is "your unaided sense organs aren't good enough to
detect the loss." The compressed output still contains less information than
the original, ergo, it is lossy.

No. If you eliminate any information, it's not lossless.

Accidents happen, but I don't kill bugs deliberately. The fact that they don't
look like me is irrelevant.
