Engine look normal to you?

OK OK OK, I know this may make some people cringe but a little backstory:
For the past almost 4 years now I thought that my car held 3.6quarts of oil. I'v always added about 3 1/2 quarts when I do the oil change but LAST time I did it I figure there is a quart between full and low so I just put 3quarts thinking it would fall in the middle. Well little did I know that there was a "quarts" and "US quarts"... In US quarts my car (apparently) holds 3.9quarts, So I shorted it this time around and since it burns just a tiny bit of oil, when i hit 4,800 miles on this oil change I had a check engine light come on and I realize there is about 1.5 quarts of oil in the whole damn car

So anyways I panicked a little, as I usually do when it comes to my cars. I drove 2 miles to a gas station and put a quart in, then drove home (20 more miles) and did a full oil change. Then I did a compression test the next day and got 225, 220, 219, 225 which is higher than the 213psi that is suppose to be possible with this engine but I read that carbon build-up will raise compression readings so no biggie.

Well today, because I'm really weird, I decided to paint my valve cover the most obnoxious color I could find. I found a shiny metallic hip-hop chain looking gold and thought that was perfect, well it ended up coming out like a really creamy coffee color instead, which I didn't mind. I take the valve cover off and take a look at the inside of the engine to see how bad it is and was pleasantly surprised at how clean it seemed to be, especially for 192,000m on the clock.

But what about this VVT cam shaft sprocket? (I'm pretty sure thats what it's called) It obviously has some burnt look to it, is that normal or what? I've never been inside a DOHC VVT engine before so IDK what they normally look like with wear on them.
