Does anyone know if all 737-800 (new or old) first class have movie streaming (free of charge) like Delta?

I will fly from SNA to ORD this summer on a 737-800, but I don't know if that aircraft will be a new 737 (with personal TV entertainment) or an old 737 (without PTV)...

I was on a AA 737 first class from RDU to MIA and it was an old 737-800 without PTV, but I would say the first class seat on AA 737 is more spacious than Delta's domestic first class seat. I would say service is probably a little better too.

But I was not able to check if 737-800 has free movie streaming at the time because I didn't have my ipad with me.

Thanks.
