By coincidence, half an hour ago I was reading
Beukers, Frits. Hypergeometric functions, how special are they?Notices Amer. Math. Soc. 61 (2014), no. 1, 48--56. MR3137256
http://www.ams.org/notices/201401/
which discusses solving this quintic. I don't think it answers your question, but it is a very nice paper!
There are further references in http://oeis.org/A002294
Apparently including one by me: pp.337-338 of the book shows hypergeometric forms for series reversions of x^k - x and a closed form (rel.15.5-6) that surprised me a bit back then.

Of course this message doesn't answer your question either 8-) Best regards, jj
