Anyone able to offer insight into why I am seeing this odd banding in Photoshop colour picker? 
Thanks

Issues with hardware acceleration and/ or messed up monitor color profiles. Check your settings and update your graphics driver if need be.

Does turning off »Use Graphics Processor« in the Performance Preferences (Photoshop > Preferences > Performance > Graphic Processor Settings) and restarting Photoshop have any bearing on the issue? 

Which would only support Mylenium’s conclusions.

Thank you for your replies - I had wondered whether the GPU had something to do with this - a recent install of COD Warzone and subsequent update of my GE Force driver coincided with the onset of the problem in Photoshop. I decided to check for updates for my computer and as a result upgraded the BIOS to the latest firmware version. This deep level update has cured the colour issue in Photoshop, though I cannot say how. But, problem solved, so many thanks for your advice and great to know there are people in the community willing to help.

I spoke too soon - the problem returned. Decided to recalibrate my monitors using my xrite iDisplay - that has completely sorted out the problem - kudos to Mylenium for drawing my attention to this.
