As noted in a couple of the other DxO recent threads, the U-Point technology that is used extensively in the Nik group of applications has been incorporated into the new local corrections implemented in DxO's recently updated raw converter, formerly called DxO OpticsPro, now called DxP PhotoLab. In addition to the usually brush, gradient and radial local corrections tools, the user has the ability to drop a radial correction on an area of tone and color and the U-Point algorithm will automatically select similar tone and color and apply the correction.
The Nik Collection in its current state is also available for download and it has been working well in the newest Photoshop CC (2018).
