Best bet would be to just buy and original quality part or use a better repair company. "ETrade supply" are great as they have a range of qualities. They are a more expensive than others, but as you have seen, you pay for what you get. I've used them in the past and I beleive they ship from the US now also. OEM or original shouldn't have colour or pixel issues. Also have you tried asking these companies what quality parts they use. As you clearly have a keen eye and you may be better off telling them you have had issues with poor quality parts. I am sure the majority of them will be honest with you, as the hassle is not worth their time having to replace it again and again. I hope this helps!
