Not sure where you're looking but the Reference Guide definitely delineates that HDMI 2 & 3 ONLY support 4K @ 60Hz.
HDMI IN 1/2/3/4 (Support 4K resolution, HDCP 2.2-compatible)
4096 × 2160p (60 Hz)*1*2, 4096 × 2160p (24 Hz)*1, 3840 × 2160p (60 Hz)*2, 3840 × 2160p (24, 30 Hz), 1080p (30, 60 Hz), 1080/24p, 1080i (60 Hz), 720p (30, 60 Hz), 720/24p, 480p, 480i, PC Formats*3
*1 When 4096 × 2160p is input and [Wide
mode] is set to [Normal], the resolution is displayed as 3840 × 2160p. To display 4096 × 2160p, set [Wide mode] setting to [Full 1] or [Full 2].
The Marketing Specs list it this way:
Up to 18Gbps:4K
60p 4:4:4(8bit), 4:2:2(8,10,12bit), 4:2:0(8,10bit) HDR included for HDMI 2/3
I suspect it's this that makes people assume HDR is only provided on ports 2 & 3, when all four ports support HDR, just not at 60p, and at those bit depths and chroma.
The Help guide couldn't be more clear however:
When you display the High-Quality 4K format with the HDMI input, set [HDMI signal format] in [External inputs].
HDMI signal format
To change the HDMI signal format setting, press the HOME button, then select [Settings] — [External inputs] — [HDMI signal format].
Standard HDMI format*1 for normal use.
High-Quality HDMI format*1*2. Set only when using capable devices.
*1 HDR included (HDR models only). HDR models have [HDR mode] in [Settings] — [Picture & Display] — [Picture adjustments] — [Advanced settings] — [Video options].
*2 4K 60p 4:2:0 10bit, 4:4:4:, 4:2:2 etc.
HDCP 2.2 is a separate issue from HDMI 2.0. All four ports are HDCP 2.2 compatible, but only 2 & 3 are HDMI 2.0 compatible. Though not explicitly clear, that's what the PDF states.
