raw render quality issue's

Hi,

At the moment I'm testing out On1 Photo Raw. I really like the program. All the bells and whistles I need, responsive etc. But when putting raw redering to the test with a under-lit nightscene I encountered a lot of noise, color cast and unsharpenes compared to DxO render of the same image. With no additional changes I just increased a bit the exposure and in the On1 render you can clearly see color cast and noise in the snow part below and no color cast and less noise in the DxO version. Even if I use NoNoise in On1 (most right) its still present and less detail is preserved.
Is there something I might doing wrong or can do to prevent this? I really prefer the On1 program, toolbox and price over DxO but render quality is always most important. Hope somebody can help.

PS using a sony a7iii camera. I tried to keep the settings comparable and I know its a screenshot of the images so its not very clear but with on1 its clear to see it introduced color pixels and more noise then in the render of DxO. Also good to know I'm also testing DxO so I'm just as known with that them with On1
