Greater Pewee field marks in The Sibley Guide

The Sibley Guide to North American Birds (p.322):  {with my comments in italics}
"Differs from Olive-sided Flycatcher by longer tail, {YES,see photo below}

rounder wingtips, {?}
thinner bill, {?}
and pointed crest." {YES, see photo below}

Sibley also notes a "long notched tail" {?}
and "plain grayish" noting underparts {YES}
plus he states at bottom of page "...so fall adults are very worn." {reason for lack of yellow on underparts}
