CSOM CAML Query - is there a returned fields limit?

Question

I've just noticed that that there is a difference in result when searching for a list item with CAML Query and getting it by ID.

Following piece of code returns item with 100 FieldValues:

var item = sourceList.GetItemById(1);
ctx.Load(item);
await ctx.ExecuteQueryRetryAsync();

While the following piece returns only 97 FieldValues:

var queryTxt = $"<View><Query><Where><Eq><FieldRef Name=\"ID\" /><Value Type=\"Integer\">1</Value></Eq></Where></Query></View>";
var query = new CamlQuery()
        {
            ViewXml = queryTxt
        };
var itemList = sourceList.GetItems(query);
ctx.Load(itemList);
await ctx.ExecuteQueryRetryAsync();
var item = itemsList.FirstOrDefault();

Is there anything I've missed?

Edit: If I invoke it like this, I also get 100 FieldValues

var queryTxt = $"<View><Query><Where><Eq><FieldRef Name=\"ID\" /><Value Type=\"Integer\">1</Value></Eq></Where></Query></View>";
var query = new CamlQuery()
    {
        ViewXml = queryTxt
    };
var itemList = sourceList.GetItems(query);
ctx.Load(itemList);
await ctx.ExecuteQueryRetryAsync();
var item = itemsList.FirstOrDefault();
ctx.Load(item);
await ctx.ExecuteQueryRetryAsync();

It should return the same FieldValues count for the item returned from CAML or getting by Id, here is the test capture in my side:

Get List Item (Id:1) with CAML, return 63 FieldValues when tracing:

Get List Item By Id directly, the FieldValues is the same 63:
