Can は imply more than just topic?


On <https://www.wasabi-jpn.com/japanese-grammar/ha-vs-ga-five-points-you-need-
to-know/> there is this sentence:

> オレンジは好き

It’s explained as “this indicates that you like oranges, but don’t like other
fruits very much; that is to say, you generally don’t like fruits”. User4092
wrote that this is not an accurate explanation and that it can imply that the
speaker doesn’t like some fruits.

I will repeat my question here:

Should I read it as “when it comes to fruits, I like oranges the most” or
“when it comes to fruits, I mainly like oranges”? It seems to me that the
latter is more correct as “I like oranges the most” does not imply that the
speaker doesn’t like some other fruit. I mean if someone told me this and I'd
like to buy him/her something fruit-flavoured should I assume that it would be
best to not buy anything that is not orange-flavoured as the probability that
he/she would not like its taste will be high?

It seems that the former isn’t the right way to understand it.  
How much can I read form は when it’s used as a topic marker? Do people use it
to imply things? Or is it best to not look too deep into that kind of
sentence?




It depends on contexts.

[code]

     A: 果物で何か好きなものはありますか？
     B: そうですね…果物は…例えば、オレンジは好きですね…
    
[/code]

In this case, contrast of this topic is not so strong as to imply that the
speaker dislikes other fruits, at most, contrastive in the sense that you
don't know about the others.

[code]

     A: もしかして、果物が嫌いなんですか？
     B: いや、オレンジは好きですよ？ オレンジはね。
    
[/code]

This time, the speaker bothers to make it explicit that what s/he says is
applied to oranges, which implies that s/he may not like fruits in general,
combined with the background context.
