Question about Samsung C49RG94SSU

The LC49RG90SSUXEN is HDR Certified 1000cd vs 600cd, also some more USB ports etc.

Same panel, different ports and stuff :

I also have trouble telling the difference. Does anyone know more?

I would also be interested. What justifies the price difference?

I think something is said about the differences between the Samsung 49" monitors in this video...
