Why is there no good scandoublers to be found?

I'm really bothered by the low quality scandoublers that are to be found everywhere when looking for a scandoubler for the AMiGA.

Why on earth can't I find one single scandoubler which is able to show AGA correctly? I'm rather tired of not being able to use AGA in a somewhat decent way with my monitor, having the green colours look like they can be shown in no more than 16 variations... what on earth is this? Where they simply lazy when they made the scandoublers (I think I've tried three myself and seen some three more being used, and they all looked horrible when showing AGA colours).

All DCE scandoubler/flickerfixers only has one 8-bit channel - the red. Both the green and blue channel are only 4-bits (16 variations). So they are better than a 4:4:4 OCS/ECS scandoubler, but not by much.

I wonder why they chose red to have the 8-bit channel, it is much more apparent with green that variations are missing. And, I wonder, was this just something done to cut down on the production costs? However, things get even weirder. Sometimes some colours even appear completely out of bound. I'm not that unfamiliar with purple appearing on the most unexpected occasions (and this is the case with both the DCE ones I've tried).

I wonder why I've heard so extremely little complaints about this very issue, that there are so few scandoublers with 8:8:8 to offer (if any). Picasso IV has it, I've heard, but that feels a bit far fetched... to get hold of that GFX-card only for the scandoubler.

I guess I'm a bit out of luck here.
