Proper display of black and background color at pdf from Adobe Indesign

Question

Hi, I have file exported from Indesign 18.5 x64 (export as PDF/X-1A) - press quality. I have problem with proper display of background color (1) and black (2) at Adobe Acrobat Pro (2023.003.20284).

1) Background color is made as a fill of graphic frame and it does not show up at all. I can see just white bg. 2) And black is displayed as a rich black regadless it is define as 100% K.

(The same sample at link or as an attachement)

Can you advise me, how can I set Acrobat or export PDF to be properly shown?

Thanks

I have already found solution - Navigate to Acrobat's Preferences once from Edit>Preferences>Accessibility and check if the checkbox 'Replace Document colors' is On or Off. – (IT SHOULD BE OFF.) – This and changing the background color by going to Tools > Pages > Background are the only two places that this can be changed within Acrobat.
