I'm thinking the op was imagining something in the middle ground. Maybe +10–40% for a guarantee of quality. The case I can think of is Anker for cables although in that case they also don't charge a premium either.
Honestly, in that price range, Dell is probably "good enough"
Grab something like the i1Display Studio to calibrate and it'll be golden for anyone who doesn't need a hardware LUT or built-in calibration.
They cost multiple thousands (or tens of thousands for reference monitors with built-in calibration and Dolby Vision certification).
