I don't think 首映 means "first-run movie". I don't think it's any sort of movie, but rather the screening of a movie — specifically, the first screening (the premiere).
As for ABC's gloss "first-time TV", that isn't very clear. It's presumably intended to mean "TV show shown for the first time". But I don't think it means that either. Again, it's the first screening of the show, not the show itself.
I think "first-run movie/TV" is wrong because I checked dictionaries and examples of usage.
No other dictionary that I checked says that 首映 is a first-run movie or TV show. Here is a sampling of definitions:
PLC ~ VERB be premiered; have a premiere; show for the first time
MOE ~ 第一場放映。如：「三十年代的回顧影展，今天在新公園首映。」
LAC ~ 第一次放映。例 「電影首映式」、「該片將於下週在臺首映」。
KEY ~ first showing (of a movie), premiere
NC ~ (动) (of a film) run for the first time; have its premiere; premiere
ABC (E-C) ~ premiere n.c./v. shọ̌uyǎn 首演; shǒuyìng 首映; shọ̌uzhǎn 首展
Based on examples of usage (see below), I propose the following definition:
1. (v.) to premiere (a movie); to show (a film or TV show) for the first time
2. (n.) premiere (of a movie, etc.)
3. (attr.) first-run
4. (v.) greet (the eye) before anything else (e.g. when entering a room)
I'm not sure how that should be formatted using band notation, but I did my best. In particular, the French definition "exclusivité (pour un film / une émission)" doesn't seem to correspond to any of the senses of 首映, but then again, my French is not that great. Certainly, exclusivité appears to be a noun, so I have aligned it with my sense #2. But can exclusivité mean "the first showing of a movie"? One dictionary defines exclusivité as "Caractère exclusif de quelque chose". That sounds like something different from a premiere.
Anyway, I hope you can tidy up the definition if I've gotten the formatting wrong.
Here are my examples of usage for each sense:
1. (v.) to premiere (a movie); to show (a film or TV show) for the first time
