IMO the density looks even more solid in the second pic, so I would consider that healthy maturation at this point. Hairline is just straightening. I don't see any rounding pattern whatsoever. Your temporal hairline, the side, is also straight and not rounding so that is good.
The scale is kind of arbitrary since hairlines come in all kinds of shapes. But as a general rule for me, a 2 is what would be described as a fully matured hairline. So even if it goes higher, it still retains the same shape and there are no signs of it going farther. You look like you're just finishing up the maturation stage so I'd just call it 1.5 but soon to be a healthy looking 2. IMO recession or balding is anything that is 2.5 or higher. I wouldn't be super concerned at this point, just keep an eye on it every couple of months.
