Most the time I watch in normal lighting condition room, but sometimes I watch in total dark room also.
I never ever facing over exposure issue at all.

Did you make some changes on the setting? suggest you reset back all to original and check again by turning on the DTM only.
Last time, someone here told me OLED Light, Contrast and Brightness cannot simply touch as this will impact the output.
I let all this in default setting and it looks just nice in Cinema Mode for all except Home Cinema Mode for Dolby Vision to me.
There is a few reason for this.
1.you are use to this setting and you don't find it wrong at all.
2.u watch the movie/show without doing critical viewing to check on it.
Want you can do is use a short clip or a short scene in a movie.
Try to use 2 settings alternately. You will mostly see the overexposure on dark scene and also overbloom on bright scene.
It's the nature of DTM. And DTM is not DV. DV use dynamic meta data, in this sense that the movie/show is mastered in dynamic mapping for DV.
DTM uses dynamic Tone Mapping on a static meta data, hence it will have incorrect value at high and low values.
It's nice to use DTM for games thou, cuz games is not meant for accuracy, and ppl like games to be punchy with overbloom effect.
All in all use how you want it to be, it's preference when it comes to viewing entertainment.
But do know that preference is not always correct.
