yes the noise is luminance i.e. grains.

I have to respectfully disagree with the statement that DPP is not a good RAW convertor. If you are getting less noise with ACR than DPP, then your DPP workflow is not optimized or you maybe using incorrect parameters.

DPP produces the best output quality for high ISO. I would personally not use ISO 4000 on a 7D with any software, it doesn’t meet my quality standards and I do not recommend it.

Regarding the new releases of ACR, it still does not work well IMO. The noise is coarse and difficult to remove while retaining fine details. Not to mention very strong color casts when using 1DX or 5D3 camera bodies.

Best
