Making white pixels transparent results ins some ugly logos

Hi!

It seems to me that pure white pixels (only) are made transparent with logos in multiple places: OSD, status bar, selected channel.
I see no particular use for this, but it can certainly be eclectic and result in some bad looking logos, as the examples show:

Not all logopacks floating around use alpha transparency (or transparency at all, where colorkey's can be assumed for some transparency (usually white), or am i wrong?). Will check this.

I don't know aren't logopacks a hodge-podge of images, collected by anyone? Not sure if anything can be assumed.

not necessarily, there are some (pseudo) standards there for example https://www.picons.eu/ (picon filenaming is also supported). I'll see if this can be consistently solved somehow, otherwise an option to turn on/off colorkey processing would already work with your collection of logo's, i'm presuming most people will want to just drop in some existing logo packs).
