Apple has been making misleading claims about the Pro Display XDR, according to The Advertising Standards Authority (ASA) in the UK. Now, Apple can no longer claim that the Pro Display XDR offers 'far beyond HDR' in the UK, although it continues to do so in the US and other countries. The same goes for the company implying that the display covers 100% of the DCI-P3 colour gamut.
