Is it though? The margin is similar to 2020 and Biden is just sitting at 40% here. I don't think Texas is there yet in 2024 unless Biden wins reelection in a blowout.
Texas is fundamentally overrated for the democrats and while people make comparisons to GA there is one huge difference and that is that demographic changes in Georgia overwhelmingly benefit the democrats as African Americans vote 9:1 democratic while in Texas they only help a little bit as Hispanics/Asians more or less only give the democrats around a 1.5:1 advantage and sometimes less .
Also other than 2012-2016 Texas hasn't trended that D in one cycle
2000: 22 points more Republican than the Nation as a whole
2004: 21 Points more Republican than the Nation as a whole
2008: 19 Points more Republican than the Nation as a whole
2012: 20 points more Republican than the nation as a whole
2016: 11 points more Republican than the nation as a whole
2020 : 10 points more Republican than the nation as a whole
What this shows is trends due to demographics only net the democrats around 1 point in Texas while the 2012/16 trend was more or less due to a huge change in the Republican Party during that time which caused many white suburbanite voters to switch democratic

You listed four election cycles here where Texas trended Democratic (though tbf not by very large margins in 2004, 2008, and 2020 - and those elections had significant internal contradictory trends with parts of rural TX becoming more Republican in the 2000s and the Latino South and West Texas shifts in 2020 counteracting some of the gains Democrats made in the large metros).
