How to make sure your photos look good on phones with different display color settings?

Hi!

I've come to share an embarrassing beginner moment of mine, I'm not sure how to solve this.

A little backstory, I do not have a good monitor for my PC for photo editing, I use an old TV which unfortunately has some weird colored streaks, so I can't use it when I need to see the image clearly. To solve this, I've been mirroring the screen to my phone and using that as a monitor.

It's been two months since I've started doing photography twice a week and editing photos like this, but I just found out my phone has had the "vivid display" setting on ALL this time. For months I've been sharing photos that probably look horrid and dull to others, because they could be using the natural display setting. People now probably think the photos look like that intentionally, when it was a mistake all this time! I feel SO dumb and embarrassed for not realizing sooner 😭

I've looked online and some comment sections are filled with "I only use vivid" and some the opposite with natural. I don't even know how it looks on IPhones now, because I'm not sure if they have settings like that! If I edit the images so they look good in natural, it'll look oversaturated for people who use vivid, I'm stumped. I've tried to edit them to be somewhere between the two, but that makes them look bad in both settings. I'm a beginner, so I do not trust myself to use the histogram efficiently.

I feel like I should also add that I only do hobby dog photography for a local group of people who do dog obedience, and they only see the photos on their phone - I don't do prints or anything like that, my problems are phone screens :-(

How do you guys deal with this? Do you think it's a big deal I should worry about? I also apologize for any English mistakes!
