問下大家有無試過係香港極pixel 機
有無介紹?

PS 部機係Amazon 番黎 用咗差不多2年了

The phone does, and still, supports HDR. The feature was never removed. The title has the word "effectively" in it because, although the feature is there, there is no official confirmation that it exists as the support page does not include it
...
Not including it in the support article could be causing cascading issues such as streaming services assuming that it doesn't support it and hence not streaming HDR to it (assumption).
