Correct answer D Fosse

If it's a 16 bit file, any banding is always in the display system, not in the image data. If changing the monitor profile has no effect, try to turn off GPU in Photoshop preferences, or set it to "Basic" mode.

Keep in mind that a standard display pipeline is 8-bit, and close tonalities like here only have so many discrete values to distribute. I'm told that Lightroom uses dithering to break up banding in 8 bit output, so maybe ACR does too.

In most circumstances ACR should be much more susceptible to these problems than Photoshop, simply because the conversion from linear gamma ProPhoto (into the monitor profile) is a much more complex conversion than from a standard gamma 2.2 color space.

As I can see in camera raw , you've set contrast -38 and shadows -60
it may also be part of the trouble you're facing, cuz these too are working against each other, you're taking out the contrast then adding it manually with shadow point controller.

    Have you tried recalibrating your monitor? The colors look a bit different between the two screenshots, which can indicate a broken monitor profile.

    I'm not seeing any banding (this 8-bit jpeg may show some slight banding of equal amounts) between ACR and Ps at my end.

    I messed with the calibration and it helped a bit but the gradient is much worse in the second photo after I open it from Camera Raw which makes it difficult to edit as I think it's gonna look good and I open it and the sky looks awful.

    Set your monitor profile (system settings, not in Ps) to sRGB (or Adobe RGB if you happen to have a wide gamut monitor). See if that helps. Do you have a hardware calibration unit such as the ColorMunki or SpyderPro?
