Well beyond, I believe. Like, even trying to repair one can kill you
It's really not that dangerous. There's a big capacitor called the flyback capacitor which can store a deadly amount of energy. You disconnect the power (obviously) and then discharge that cap and everything else is relatively safe. To discharge a capacitor, bridge the leads with an electricians screwdriver. If you don't like sparks, hold a resistor with pliers between the two leads. (It will go slower but also get hot AF.)
That's just basic electronics stuff. It doesn't take a terribly large charged capacitor to zap you dead. IIRC, there are some high voltages in CRTs, but if you know how to discharge caps and to never ever work on electronics while plugged in (especially anything AC or DC over even 12v running), you'll be fine.
Making them, however, is a whole additional technical and mathematical set of skills.
The outer envelope layer of a CRT itself is a capacitor, and depending on the tube size, can hold ~13,000 to ~25,000 volts. What makes it worse is that you can properly discharge the tube, completely remove it and put it on a storage shelf somewhere for months, then come back to it and the motherfucker done managed to recharge itself from the fucking atmosphere!
Any sufficiently big capacitor does this and that's why you short them out for storage unless you want to die.
The biggest ones I worked with were 75 kg slices of stinkiness when they leaked and had to have two separate loops of wire on the terminals for safe disposal.
