12.14.6 (18G29g) Preview not correctly showing black as black

Since installing the latest beta my PDF’s with black content that were created in InDesign CC are now presenting as grey. These are black boxes in the images that as of the previous build were presenting black correctly now are overlaying as grey. I have just made screen shots of the same PDF and the photo that is placed below the grey box (which should be black) is now badly colourized and the photo now appears as very blotchy. There should be no grey in these images and all previous beta builds presented as black.


The screen shot taken from the same PDF is badly aliasing.


Images attached.

Are these issues going to be addressed in a new beta build of 10.14.6?
